Honda CR250R

From Wikipedia, the free encyclopedia

Honda CR250 Prototype for the CR250 was built in 1971. But it wasn't until late 1972 that production started on "out of the box racers" began. Made available for sale to the general public in 1973. The CR250 is the longest running 2-stroke motocross motorcycle of all time, being in production for nearly 37 years. The two-stroke CR250R is no longer produced by Honda. 2007 was the last year of production. Many two stroke enthusiasts regard the 2000-2001 CR250R as the best 2 stroke 250 motocross bike of all time, rivaled only by the 2005-up Yamaha YZ250. The 2000-2001 CR250s had the 2nd generation aluminum frame that was loved by many riders, and the non-electronic powervalve that is known as the RC, or revolutionary control valve. The 2002-2004 CRs had case-reed motors with the RC valve that had a narrow powerband that was hard to control. The 2001 CR is a refined version of the 2000 model that has a wider base valve in the forks that allows wider range of adjustments than the 2000 model, and a superior shock with a better valve and refined shim stack.
